>Hi I have purchased several things from this website including the adxl330 breakout board.
I'm not sure what you're referring to. This web site is our blog; we don't sell anything here. We do have <a href="http://evilmadscience.com/">a webstore</a>, but even there we don't sell adxl330 breakout boards.
>What I want to do is use 3 additional outputs to pass the 3 inputs directly to 3 additional output.
You mean, take the analog inputs and copy them to analog outputs? The type of AVR that we used does not have analog outputs. You can use the PWM outputs to simulate analog outputs-- as we did in that article, but that's really the closest that there is. It's vastly degraded in terms of noise, resolution, and bandwidth, so it may not really be what you want. If you want to pass the data to a different logger, you should consider using analog buffers instead.
